I´m surprised by the reactions... yes, my first thought was also that this was a man who wanted to teach to women/girls. But a woman teaching, of course, when in Turkey, having male students over can make people get the wrong idea. And far too often the teacher can get in trouble...

I hope you find some students. The use of ´boy´ seems to be quite widely spread in Turkey, for example my wife (28 years old back then) got a request from a colleague about teaching him (50 years old) Turkish. She replied ´I´m married, and I don´t want to be seen alone with a boy´.
